Select the most appropriate option to fill in blank No. 1.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. to deliver.
Context: The blank requires an infinitive form of the verb to express the purpose of the invitation — that is, the speaker is invited for the purpose of delivering lectures.
Meaning of the options:
Deliver: base form of the verb, not suitable after “invited to.”
To deliver: infinitive form, correct after “invited to” to express purpose.
Delivering: present participle, incorrect here.
Delivered: past tense or past participle, incorrect here.
Correct word: To deliver
Reason: After the verb “invited,” the correct structure is “invited to + infinitive verb.” So, “to deliver” fits the sentence correctly.
Final sentence: I was often invited to colleges and universities to deliver lectures.
Hence, the chosen option will be correct.
